Most xiphe handles followed a two-piece construction (similar to a knife) using either native woods or, for more exotic imports, ebony and animal bone.
The two slabs were attached to the tang of the sword, secured via two or three pins and then made smooth via filing giving the characteristic oval shape of a xiphos grip.
Hand guards usually followed a "bridge" shape and were either also of organic material or iron or a combination of both, also secured via pins on each point.
Some swords found in Italy or Macedonia tended to have an iron extension/reinforcement running along the handle (see picture of modern reconstruction of a xiphos made by Manning Imperial above).
The leaf-shaped short swords were not limited to Greece, as mentioned, but can be found throughout Europe in the late Bronze Age under various names.
The several whole or partial xiphe blades found in places such as Olympia, Macedonia and Southern Italy were all made exclusively from iron.
